12 Claims. (Cl. 118-3) The present invention relates to an improvementin printing presses and, more particularly, to an improvement inprinting presses including means forapplymg adhesive spots to a sheetupon which an impression is being made when the sheet is removed fromthe chase. While the invention is preferably used with a bed and platentype or" printing press and is described in connection with the same, itwill be appreciated that the invention is capable of use with othertypesof printing presses such as a cylinder type printing press, oflset typeprinting press, or the like.

Heretofore, in the manufacture of carbon-set forms, that is, formswherein carbon paper is interleaved between printed forms and bound inpad or book form for use as invoices, sales slips and the like, it hasbeen impractical and uneconomical for a small printer to print and bindsuch forms. The sequence used by small'printers in the past included,first printing the necessary material on the individual sheets and thenafter the sheets had been printed, theywere sent to the bindery where anoperator few the printed sheets and carbon sheets, piece by piece, insequence, to a machine by hand. Each time the sheets were fed to themachine, the operator had to'press his knee against a lever and apply aspot of glue to the sheet so that the carbon paper could be afi'ixedthereto. The books or pads were assembled in this step by stepprocedure, involving a considerable amount of time and labor, and thusresulted in high production costs.

' In large scale operation, such book or pad forms were made by printingthe form on paper rolls. The paper rolls were then fed to anothermachine with anumber of carbon rolls, in proper sequence- The machinethen glued the sheets together and individually cut the sheets to formsales books,'or the like. Such an operation necessitated having alargeprinting order to justify the high cost ofsetting up andmaintaining the comprehensive equipment involved.

While themethod of making the books or pads by hand, that is, printingthe individual sheets and then'interleaving the sheets with carbon paperand applying glue by hand, is costly as it requires an extensive amountof time to perform the complete operation, small printers who had smallorders necessarily had to use this method of hand manifolding and gluingof the printed sheets and carbonpaper together. In other words, theycould not alford to set up the elaborate equipment necessary to print onrolls of paper, then remove the rolls of paper from the printing pressesand set up separate machines wherein the paper was interleaved withrolls of carbon paper out to size and glued. V

An object of the present invention is to provide a printing press meansby which the adhesive necessary to'glue the books or pads together isapplied when the sheets for the forms are printed. g

Another object of p the present invention is to provide a printing presswith a chase which will apply spots of glue to a sheet as the impressionis being made upon the sheet. "A still further object of the presentinvention is to i United States Patent 2,955,564 Patented'o 1960 2provide a printing press wherein the chase is provided with means forapplying glue to the sheet carried by the platen at the time theimpression is being made, the press being also provided with means tocause the inking rollers to avoid contact with the adhesive applyingmeans.

A still further object of the present invention is to provide a chasefor a printing press which is held in a substantially vertical positionwhen the sheet holding and impression means is making an impression on asheet carried thereby, the chase being provided with means for applyingadhesive spots to the sheet by a pumping action rather than a leakingaction.

These and other objects of the present invention will appear more fullyin the following specification, claims and drawings, in which:

Figure 1 is a diagrammatic view of the present invention utilized in aplaten press, the inking rollers being shown in solid lines in aposition for receiving ink from the inking plate and, in' broken lines,in a position just after applying ink to the type held by the chase.

Figure 2 discloses a fragmentary side view of the platen press showingthe inking rollers just after applying ink to the type carried by theplaten.

Figure 3 is an enlarged fragmentary view, partly in' tially. on the line6-6 of Figure 5 and illustrating in addition a section of the platenopening the valve.

Figure 7 is a view taken on the line 7-7 of Figure 6, and V Figure 8 isan exploded view of a form book or pad showing. the interleaving ofcarbon papers between the printed sheets or forms, with theadhesivespots provided on the forms.

' Referring now to the accompanying drawings, the arrangement of thepresent invention is illustrated in association with a platen press ofthe type disclosed in United States Patents No. 2,088,377, issued July27, 1937, to Kluge et al.; No. 2,3l8,165, issued May 4, 1943, to Kluge;and No. 2,429,874, issued October 28, 1947, to FrieL. i i

It will be understood that the aforementioned patents represent typicalautomatic platen presses, wherein the impression block or bed is adaptedto receive and support a type-receiving case in a substantially verticalposition, and a platen is adapted to receive a sheet while in asubstantially horizontal position and transfer the sheet to asubstantially vertical position, where the platen and bed are movedrelative to one another to make an impression upon the sheet.Conventional means may be used for delivering the sheet from a stockmagazine to the platen and for removing the sheet from the platen afteran impression has been made and transferring the sheet to a suitabledelivery box, where the sheets are deposited. Only those elements of theplaten type printing press which are necessary for disclosure of thepresent invention are shown in the accompanying drawings, it beingunderstood that the present invention is capable forapplication to anytype of printing press, and especi ally those printing presses whereinat least the chase carrying bed is substantially in a vertical positionwhen the sheet holding and impression means is in impression position.

printing press, generally indicated by the numeral 10,

The platen type printing press is provided with the usual stock magazine12 having a sloping sheet receiving surface, wherein a pack 13 of blanksheets 14 of paper is supported on edge, by a rest 16. Rest '16 isintermittently advanced upwardly along the sloping surface so as toalways present the foremost sheet of the pack at a predetermined orfixed sheet-receiving position. The foremost sheet 14 of the pack ofsheets is picked off by a feeder arm 18 provided with the usual suctionfeed grips 20 and is deposited on a platen 22 of the press 19 when theplaten is in a substantially horizontal position as shown, in brokenlines, in Figure l. The sheet 14 is held on the platen 22 by the usualplaten grippers (not shown) and the platen 22 is then moved in timedsequence, by suitable levers and cam mechanisms (not shown), in thedirection of the arrow A to an impression position where the printing ofthe form on sheet occurs. As shown in Figure 6, the platen issubstantially vertical and, when in this position, it is in what isknown in the trade as the impression position with respect to a bed orimpression block 24 which supports a chase, generally indicated at 26,and shown in broken lines in Figure 1. The bed 24 supporting the chase26 may be stationary as it may be movable to the impression position asis clearly shown in th aforementioned patents.

After the impression is made on the sheet 14, the platen 22 is thenmoved back to its broken-line position of Figure 1, where the sheet 14is picked up by suitable suction grippers (not shsown) and deposited ona delivery table 28, which is adjustable vrtically. The delivery table28 is originally adjusted to an upper position but as sheets 14 aredeposited thereon it may be automatically lowered to better receive thesheets.

The platen press of the present invention is provided with a pair ofguide rails or tracks 30 which extend in parallel spaced relationship toeach other along each side of an inking plate 32 and then verticallydownwardly along each side of the impression block 24. Inking rollers34, carried on saddle rods or frame members 36, are adapted to be movedacross the inking plate 32 and downwardly along the rails or tracks 30so as to apply ink to the type carried by the chase 26. As shown inFigure 1, the inking rollers 34 are moved by the frame members 36through suitable links and earns (not shown) from the full line positionwhere they are on the inking plate 32, to a dotted line position, wherethey are passing over the chase 26 and have applied ink to the typecarried thereby. The action of the inking rollers 34 occurs when theplaten 22 is out of impression position, as shown in Figure 1 and itwill be understood that this relative movement is all in timed sequence.In the dotted line position of the inking rollers 34, it will be notedthat they are just passing over the lower portion of the chase 26 andwhen they continued to follow the track 30 to a position where they areclear of the chase 26, the platen 22, shown in full lines, will beapproaching the chase toward impression position, as is well known inthe art.

As best shown in Figures 2 and 3, the inking rollers 34 are providedwith trucks 38 which ride on the rails or tracks 30, the trucks beingsupported on the usual crossarms 40, which are pivotally connected, asindicated at 42, to a rod 44 carried in the frame member 36. A heavycoil spring 46, or the like, urges the trucks 38 into engagement withthe track and permits the rollers to pass around the curve provided inthe track.

As shown in Figures 1 and 4, cam means, such as the flange 48, isprovided on the track or rail 30, adjacent the lower end of the verticalrun, for the purpose of lifting the inking rollers outwardly of thechase, as will be described in more detail later in the specification.The flange 48 may be attached to the rail 30 in any suitable manner,such as by the machine screws 50.

Referring now to Figure 5, the chase 26 includes the usual rectangularframe having vertically spaced parallel 4 side walls 52 and horizontallyspaced parallel side walls 54. The present invention includes providingthe chase 26 with a glue fountain or adhesive reservoir 56 adjacent oneof the vertical side walls 52, the reservoir 56 being either permanentlyafiixed to the side wall or detachably held in the side wall by theusual wedges or quoins 58 and 60, as well as the wooden spacer blocks62, 64, 68

and 70. The type plate or type, is generally indicated at 72 and, ofcourse, this is also held in place by the usual spacer blocks, wedgesand quoins referred to above.

Also carried by the chase is a hollow manifold 74 which is square incross-section and closed at one end, as shown in Figure 6, the manifoldbeing held in horizontal position adjacent the lower horizontal sidememher 54. Manifold 74 is provided with a port in fluid communicationwith the lower end of reservoir 56, by a tube or conduit 76.

As best shown in Figures 5 and 6, manifold 74 is adapted to carry aplurality of adhesive applicators, generally indicated at 78, forapplying adhesive spots to the sheet carried by platen 22, when theplaten is moved to impression position and then away from impressionposition. In more detail, the manifold 74 is provided with a pluralityof threaded holes in which the applicators 78 are detachably received.The applicator 78 includes a nozzle 82 having exterior threads 84.Nozzle 82 has an interior bore 86, circular in cross-section and havinga tapered valve seat 88. Nozzle 82 also is provided with a small bore inaxial alignment with the bore 86.

Positioned in the bores 86 and 90 is a plunger element 92 having aportion 94 in the bore 86 square in crosssection, as shown in Figure 7.The plunger element 92 is provided with a stem 96 having a diameterslightly less than the diameter of the bore 90. Stem 96 extends throughthe bore 90 and is adapted to project out of the end 98 of the nozzle,when the plunger is moved to the right of the position shown in Figure6. A tapered surface, 160 complementary in shape to the tapered surface88 is provided intermediate the stem 96 and the square portion 94 of theplunger. When the plunger is moved to the right of Figure 6 the taperedsurface 100 of the plunger engages the tapered surface 88 of the nozzleand prevents fluid from within the manifold flowing through the spacebetween the wall of bore 90 and the stem 96.

The rear end 0f the plunger element 94 is provided with a projection orpeg 102 which is adapted to receive one end of a coil compression spring104. The other end of the spring 104 abuts against the rear interiorsurface of manifold 74 and thus, the spring constantly urges the plungermember 92 toward a closed position.

Referring now to Figures 1 and 4 it will be noted that, when the chase26 is held in position on the bed or impression block 24, the nozzles 82extend horizontally of the chase, in a position substantially adjacentto the position where the flanges or earns 48 are positioned on thetracks or rails 30. The reason for providing the flanges 48 in thisposition is so that when the inking rollers 34 are moving across thechase to ink the type carried therein, and come to the area where theapplicators 78 are positioned, the rollers 34 are raised out ofengagement so that they will not hit the ends of the stems 96 whichextend out of the nozzles. Thus, no ink is applied to the ends of thenozzle nor is any glue or adhesive which may happen to be on the ends ofthe nozzles, applied to the inking rollers.

In the application of a spot of glue to one of the sheets 14, it will benoted that the sheet 14 is in substantially a vertical position. Byproviding the reservoir 56 in a vertical position with respect to andabove the manifold 74, the interior of the manifold is completely filledwith the adhesive. The particular design of plunger and nozzlearrangement, as heretofore described, provides for a positiveapplication of a spot of adhesive, rather than application of a spotofadhesive by leakage. In other words, when the platen 22 advances thesheet 14 90 onto the sheet 14.

forward toward the chase, the sheet 14 will engage the stem 96, urgingthe plunger 92 to the position shown in Figure 6. Since the portion ofthe plunger. 94, in the bore .86, is square, adhesive from the manifold74. can pass about the plunger into thearea between the valve seat 88and the tapered surface 100. When the platen 22 is retracted away fromthe chase, carrying with it the sheet. 14, the plunger 92 is urged tothe right of Figure 6 by the spring 104. This causes the adhesivebetween the surfaces 88 and 100 tobe pumped through the bore In eflect,the particular adhesive applicator'82, disclosed, provides a measuredamount of adhesive for each spot.

By making the applicators 82 detachably held in the manifold 74, greateradaptability of the invention is obtained, in that, if the number ofspots of adhesiveneed be changed, certain applicators may be removed andreplaced by a plug.

.The reservoir 56 may be easily filled with adhesive by removing a plug'106 provided at its upper end. This provides a convenient means ofrefilling the reservoir while the chase is positioned on the bed 24.

Referring now to Figure 8 of the drawings, the view shownthereinrepresents the manifolding of a pad by the interleaving of carbon paperbetween the printed form sheets 14, having the glue spots along one oftheir edges. In more detail, a first form sheet 14 is printed andsimultaneously the spots 108 of glue are applied when the sheet and theplaten are removed from impression position. The sheet is then removedfrom the platen, in a known manner, and placed on the delivery table 28.A piece of carbon paper 109, substantially the same size and havingpre-punched apertures 110 in one edge, is then placed on top of thesheet 14. The apertures 110 are spaced apart a distance substantiallyequal to the adhesive spots on the sheet 14 so that the glue will extendthrough the apertures. When the next form sheet 14 is printed and theglue spots are applied, it is permitted to be placed on the deliverytable 28 on top of the carbon paper. Since the undersurface of the formsheet does not have an adhesive on it the adhesive extending up throughthe holes in the carbon paper, attaches the sheet thereto with thecarbon paper 109 secured therebetween. This process is succesivelyrepeated until a desired number of form sheets 14 and interleaved carbonsheets 109 is provided.

A stack of cover sheets 14 may be preliminarily run through the presswith the adhesive applicators blocked ofi, so that no glue is appliedthereto. These sheets may be placed in a pile conveniently near thedelivery table and may be assembled on the sets, as the top sheet in theset, so that there are no adhesive spots visible. Each of the sheets 14,may be provided with suitable perforated lines 112 made by a perforatingrule held in the chase, as is conventional. By providing the perforatedlines, the form sheets and carbon paper may be separated, as desired.

As shown in Figure 5, the type form is set up to simultaneously printtwo forms in side by side relationship, on a single sheet of paper 14.The books or pads are assembled, as heretofore described and, after theyare assembled, the pads are cut down the middle to form two pads offorms, such as sales slips, invoices or the like.

Having set forth the nature, objects and advantages of the invention, itwill also be obvious that the invention is susceptible to some changesand modifications, without departing from the principle and spiritthereof. For this reason, the terminology used in the specification ismerely for the purpose of description and not limitation, the scope ofthe invention being defined in the appended claims.
